You’re right; they are physically unable to deal with many male perps, and in this day and age (when guns are a no-no) they are useless.
The choking of Eric Garner in Staten Island, for which six cops are being charged, was overseen by a female sergeant who let the men do the hard work. The story never got the traction Ferguson did because half of the cops (including that sergeant) are black.
You’re severely confused. You got the Freddy Gray case(still ongoing) switched up with the Eric Garner case(long over with; no billed, only one officer). Although the on scene supervisor in the latter was a black female.
